OT: Oh how i love runflats!

510135 · 01-20-2012, 05:28 AM

So i was on my way out to meet some friends and I hear a distinct pop noise.. I knew exactly what it was, put the window down and sure enough could hear the clunk...clunk. I pull over and there is a large bolt through the tread. Continued on slowly , finally arrive at the destination , my car was turning heads for all the wrong reasons , it sounded like a horse was walking down the street , clunk clunk... clunk. Anyway I have only had the car for 2 days and im already getting something repaired . Im pretty sure they can puncture repair it , well I hope they can as the rears tyres are at 90%. On the bright side I didn't have to get down and dirty and change the tyre on the side of the road!

Anyway just thought I would share and Vent!!

Pretty sure Bridgestone RFTs aren't supposed to be repaired. Most of them are actually marked "Do Not Repair"...

This is one of the reasons I have wheel and tyre insurance...

510135 · 01-20-2012, 05:54 AM

Really, I just had a look at the tyre, I couldnt see "do not repair" anywhere on mine.

Bridgestone has also told its dealers not to repair runflats even if they suffer something as simple as a nail through the tread, which means an expensive replacement tyre.

Admittedly that article is a little old but I can't find any newer info that contradicts it... other than this faint ray of hope:

Quote:

Is it possible to repair a Run-Flat tire that has been punctured?

It depends on how far and at what speed the car was driven after the puncture was sustained. Repair is possible only if deemed so by the tire sales store.
Preconditions include a puncture of less than 6mm for both side-reinforced type and support-ring type Run-Flat tires, plus minimal damage to the support ring in case of the latter. However, it is strongly recommended that the tire is replaced as its durability will have been weakened after being repaired.

Effectively, you're likely to have fight on your hands convincing a Tyre Shop to repair it and even if you can it's probably not a good idea...

some tyre shop will repair it... at your own risk

A nail through the tread is one thing. A large bolt is another.

I don't think I'd be doing any high speed runs or track days on that tyre.

MrBlonde · 01-20-2012, 07:21 AM

I've had runflats repaired a number of times. Don't believe the hype.

Honny · 01-20-2012, 07:35 AM

If you're in Perth I can offer you a free set of RFT... or maybe god sent a large bolt so you can get a set of PSS?

RaihaX · 01-20-2012, 07:38 AM

my tyre was repaired no problem

Interesting, as I can count the number of 'flats' over a 20 year period on one hand. Well, until I got a car with RFTs.

Are these tyres a magnet for spikey metal bits, due to the composition?

In actual fact, you should attract less spikey bits with RF's as they don't have any roll on the side walls when cornering..

510135 · 01-20-2012, 07:09 PM

anyway turned out they couldnt repair it , the bolt was bigger than expected. Didnt want to argue for hours on end and i wanted it fixed. Bloody hell those bridgestones are expensive , i had 19" runflats on the 3 series and it was cheaper than those bridgies. So anyway my first mod was a pair of rear tyres..... yay

MrBlonde · 01-20-2012, 07:12 PM

Sometimes the damage will be too much and a new tyre is the way to go.

I have heard can, can not as well. Some say side punchers can't be repaired and some say punchers on the flat tread can be.... one shop i spoke to said none can be repaired...

I don't mind my P zero's apart from the cost to replace them! I also have tyre and wheel insurance, 1200 a year.. one p zero is $900 bucks, I am considering moving to non ran flats. In the US i have seen run flats are a lot cheaper then Oz......any reason for our massive prices?

cheers

Yeah, that would have been my expectation i.e. stiff, tough, hard, thick composition etc.

However, from my experiences, along with anecdotal (tyre shop) evidence, this doesn't appear to be the case. I would question the supposed robustness of these tyres.

But no biggy......as no more cars shod with RFTs in my garage these days.

because we get screwed, just get your tyres from tirerack easy or from Vans from the forum (he is in Melbourne).

Thanks for the info RaihaX, will do for sure. I have quite bad inside wear on my backs and slightly better on my fronts, but i am about 1-2 months away form needing four new tyres. Hence thinking non run flats..

Has anyone running non run flats noticed inside wear is better or worse with non RFs compared to RFs?

Cheers,

BMJ

Uneven tyre wear with runflats is as Donald Rumsfeld would say a known known. My experience with non-runflats is that tyre wear is more even - results my vary though.

Conventional tyres are a night and day improvement over the run-flats - believe the hype. However, they will expose the shortcomings of the stock suspension.

Tit · 01-21-2012, 03:33 AM

Same. Just as long as it's not too close to the side-wall...
